This was a light earthquake. It is usually felt clearly nearby and can rattle windows and dishes, but damage is uncommon.

At this magnitude and depth, people at rest would likely notice it out to about 100 km (62 mi) from the epicentre. In San Juan Bautista, 5 km away, the estimate is intensity IV (light). Estimated from magnitude, depth and distance with the intensity equation USGS Did You Feel It? uses; felt reports, where there are any, are the measurement.

Likely felt in: Prunedale 12 km, intensity IV · Hollister 14 km, intensity III · Salinas 17 km, intensity III · Watsonville 23 km, intensity III · Gilroy 23 km, intensity III · Morgan Hill 38 km, intensity III · Capitola 41 km, intensity III · Live Oak 44 km, intensity III. Estimated for each town centre; each link is that town's own record.

How big was it?

This earthquake released about 17 tons of TNT. Magnitude is logarithmic: each whole step up releases about 32 times more energy, so a magnitude 5.0 would have released about 32 times as much.

  2. Mineral, Virginia 2011 M 5.8 440× the energy of this one
  3. Magna, Utah 2020 M 5.7 310× the energy of this one
  4. This earthquake M 4.0 about 17 tons of TNT
  5. Around the size people start to feel M 3.0 this one released 36× more

Energy from the Gutenberg–Richter relation (log10E = 1.5M + 4.8), rounded to two figures; bar length is magnitude, which is already a logarithm of energy. Magnitudes of past earthquakes from the USGS catalogue.

For this area

The largest earthquake within 50 km since 2016 was M 4.7 on 2019-10-15 — about 10 times the energy of this one.

Before 2016, the USGS record lists 27 earthquakes of M5 or more within 50 km; the five largest:

  1. 6.9 The 1989 Loma Prieta, California Earthquake · 40 km NW of this epicentre
  2. 6.5 Near Morgan Hill, California · 36 km NNW of this epicentre
  3. 5.9 10 km SE of Tres Pinos, California · 30 km ESE of this epicentre
  4. 5.8 Near Watsonville, California · 22 km NW of this epicentre
  5. 5.8 Near Paicines, California · 30 km ESE of this epicentre

Since 2016: the QuakeIndex catalogue (US, M1.5+), built from the USGS FDSN event service. Before 2016: USGS ComCat, M5+ from 1900. Distances are between epicentres. This is the record, not a forecast.
